My son is 4 1/2 years old. At 6 months old he was dianosed w/ torticollis (head tilt) and got PT for that. He met all his mile stones with in the appropriate time frame (having 2 other kids i see he was on the later end then my other 2) when he became somewhat mobile he started to rock in his crib (on all 4's) and make a humming noise. we thought it was cute/funny b/c his crib would bang against the wall. I mentioned to his ped and he said it was a self soothing technique,not to worry. As he got older at each Md visit I mentioned I was concerned about his speech. According to his ped he was developing fine b/c he was putting words together etc.. Still all along he continues to rock but now it's just while watching tv on our couch. he's always made great eye contact,lovable,very social although i notice he does better w/ kids 1-2 years younger.great imagination,plays imaginary play.tons of energy,and can be easily distracted (at times) at 3 i attempted to enroll him in a regular preschool. well, he did not do well. he got frustrated,refused to sit at circle,had tantrums and even hit other kids and the teachers. i had him evaled by the sped preschool program in my town. they found him to have a moderate language delay (after my ped kept telling me his speech was fine,ugh) he was put on an iep plan and put in school w/ all sped kids. once they got to know him they also found that he had some sensory issues..he seeks out sensory stimuli (examples:banging toys,jumping,touching,loves to swing,went thru' a phase he loved the sound of the toliet flushing) and at times avoid stimulis like some auditory (kids singing,Happy bday song,maybe a language thing??) i must say his sensory issues seem to come out a lot more at school. i'm told this is normal b/c of all the stimulation at school. This year (2nd year of preschool) he got moved up to the intergrated program (it's a role model program w/ 1/2 "normally developing" kids and 1/2 w/ services.. What a difference this year. He has made leaps and bounds. His speech/language has improved greatly. At school they have made a "sensory diet" environment for him and he does well. He sit the whole time at circle,plays w/ the other kids and is exceling. The school has never mentioned autism to me, at the ped office i was given a sheet to fill out w/ questions about autism/child and the need for futher evaluation, but according to this there was no need for futher eval..My concern is that he still does on occasion these quirky sensory "stims" ( i think that is what u call it) rocking while watching tv,he jumps a lot,rubs his hands up and down his leg making a humming noise,claps at times and now the new one i notice he has on OCCASION done that hand flap thing (when he's really excited or mad) I've done so much googling and to me it sounds like ADHD,autism and sensory processing disorder are similiar in a lot of ways. I know that my son has language delays/ sensory processing disorder (and wouldn't be surprised if one day diagnosed w/ adhd) Now I'm concerned if in fact he is mildly autistic. It's hard b/c I've read kids w/ sensory processing disorder have many symptoms of autism and can be misdiagnosed w/ autism.does anyone have experience w/ this? should i have him tested? Being on an IEP plan, w/ sped teachers I would think they'd mention or atleast push me in that direction to have him tested?? Being new to all this it's so confusing so any input would be great..
